permissions

问题 I'm looking for a code fragment, using which I must be to change the file permissions on unix. My project runs on java 1.4.2 .. just a sample code example or methods which needs to be used will do.. Regards, Senny 回答1: You're not the only one: How to change the file's permission and last modified in Java? You could, in principle, use Runtime.exec("chmod ...") if the existing java.io.File methods aren't enough. But it wouldn't be portable. 回答2: You could also look at the Gnu ClassPath

问题 I'm trying to make all of the images I've stored in my s3 bucket publicly readable, using the following bucket policy. { "Id": "Policy1380877762691", "Statement": [ { "Sid": "Stmt1380877761162", "Action": [ "s3:GetObject" ], "Effect": "Allow", "Resource": "arn:aws:s3:::<bucket-name>/*", "Principal": { "AWS": [ "*" ] } } ] } I have 4 other similar s3 buckets with the same bucket policy, but I keep getting 403 errors. The images in this bucket were transferred using s3cmd sync as I'm trying to

问题 As the title suggests, I need to grant the execute permission on every stored procedure in a database. We've moved from test to production and have less control over the production database.. and all of the imported stored procedures got zero permissions right now. An interesting thing to know is if there is any way to make sure all of the imported stored procedures get execute permissions from the beginning? Thanks for any help. 回答1: Generate the statements, then copy them and paste into

问题 I've put together a basic applet where the user selects a file from their hard drive, it reads the first line of this file and passes that off to JavaScript for some additional preprocessing, and then when you click a button it tries to upload that file through an HTTP POST request. I found a very basic open source applet for uploading files that I copied and modified for this last bit. The trouble is, though, it doesn't quite work. It seems like it's running fine, but then I run into two

问题 I tried to import an existing project from the github repository into aptana studio but an error says Permission denied (publickey). fatal: The remote end hung up unexpectedly I made sure to add my ssh to my account in github. I also ran $ssh -vT gitt@github.com and this is what it says that the private key cannot be found. On other windows 7 machine I never had a problem importing a Git project but on my home PC I can't get it to work. 回答1: Apparently this has to do with the proper ssh -

问题 We're currently trying to integrate existing classic ASP pages into our new method of logging to the event log. We're achieving this by calling a .NET assembly exposed as a COM object which does the actual logging to event log. This all works correctly, however when we try to write to the event log we get an error "Cannot open log for source 'SourceName'. You may not have write access.". The logging code itself works when calling from an aspx page. This obviosuly appears to be a permissions

问题 I am trying to interface with a USB device as a non-root user on RHEL5. The device is a GPIO interface (its documentation can be found at http://www.xdimax.com/sub20/sub20.html) which uses libusb-1.0. The procedure for opening the device, using its API, is: sub_device d; d = sub_find_devices(0); sub_handle h = sub_open(d); When I do this, the sub_find_devices() call works, but on the sub_open() call, I get the libusb error -3, which indicates that I do not have permissions to open the device

问题 How can I check to see the permissions (read/write/execute) that a running node.js process has on a given file? I was hoping that the fs.Stats object had some information about permissions but I don't see any. Is there some built-in function that will allow me to do such checks? For example: var filename = '/path/to/some/file'; if (fs.canRead(filename)) // OK... if (fs.canWrite(filename)) // OK... if (fs.canExecute(filename)) // OK... Surely I don't have to attempt to open the file in each of
